CVE-2026-51565Public exploitNetwork attack vector

Script execution via unescaped action parameter

Published Jul 27, 2026 · Updated Jul 27, 2026

Reflected XSS in Milk admin 0.9.8 and earlier allows remote attackers to inject script through a crafted action parameter. Modules/Docs/DocsController.php places the request's action value in a generated documentation response without neutralizing HTML or script content. Execution requires a user to open the crafted request; the injected code then runs in that user's browser under the application's origin.
